I have the Copic Ciao markers (4 sets) and I found good matches for most of the SU colors among my sets. The colors that I didn’t find a close match to were Perfect Plum, Pink Passion, Pixie Pink, Bravo Burgandy, Bordering Blue, Close to Cocoa & Ruby Red. There are colors that are similar to most of these colors but I wouldn’t say they were close enough to call them a match.
Among my colors are a beautiful selection of browns, reds and pinks, just not a match to the above colors.
These are the color matches (very close in color) that I came up with:
